MEAT SAWING MACHINE Filed May 8, 1939 2 Sheets-Sheet 2 ancem 612wPatented Aug. 15, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention has for its object to produce an efficient regulator platefor regulating the thickness of meat 'slices produced by meat sawingmachines. The invention provides a meat regulator plate that may beaccurately and quickly adjusted with reference to the saw blade of themachine and, also, may be readily swung about a part of the adjustingmechanism to above the bed of the machine to regulate the thickness ofthe slices, if desired, and away from the bed of the machine to enablelocation of an animal carcass, or a large part thereof, on the bed forcutting such large parts or to readily slide the plate to an estimatedpoint for producing cuts of meat having an estimated weight.

The invention may be contained in meat slicing machines of differentforms and, to illustrate a practical application of the invention, Ihave selected a machine having a meat slice regulating blade embodyingmy invention. The meat-slicing blade, and a part of a machine to whichit may be applied, is shown in the accompanying drawings.

Fig. 1 of the drawings illustrates a perspective view of the part of themachine to which the plate is connected. Fig. 2 illustrates a means forsupporting the plate, with reference to the machine, and for adjustingthe plate, with reference to the bed of the machine. Fig. 3 illustratesa view of a section of a part of the adjusting means taken on the planeof the line 33 indicated in Fig. 2. Fig. 4 illustrates the platesupported in a position different from that in which it is shownsupported in Fig. 2.

The meat sawing machine I, shown in Fig. 1, has a bed 2 that is locatedon the top of the base 4. A band saw 5 is mounted on a pair of wheels,one of which is rotatably supported on a pedestal I and the other ofwhich is located in the base 4. A suitable driving mechanism, such as anelectric motor and reducing gear, located in the base 4, operates thelower wheel to drive the saw 5 in a manner well known in the art.

Contiguous to one end of the bed 2, there is located a sliding plate 8,which may be mounted on the side of the base 4 and on a bracket l0 thatprotrudes from the base 4. As is common in the art, the plate 8 isprovided with suitable rollers or wheels that move along channels II andi2, the channel if being mounted on the bracket Ill and the channel l2being mounted on the side of the base 4. When slicing, the meat isplaced upon the plate 8 and is moved rearward with respect to themachine and against the saw 5.

To regulate the thickness of the slices, a sliceregulating plate I4 issupported, to overhang the bed 2 of the machine, by means of a bracketarm l5, which is supported by slidable and pivotal movements on a barii, that is secured to the base 4 of the machine. The bed 2 protrudesforward and above the front of the base 4 to form the ledge l8 and thebar I1 is located below the ledge and extends parallel therewith. In theform of construction shown in the drawings, the bar I! is secured, atone end, to the base 4, by means of the bracket 20 and, at the otherend, to the channel l2 to dispose the bar I! in spaced relation withrespect to the upper end of the base 4 and in parallel relation to theledge l8. The bar I! is cylindrical in form and the bracket 15 has alateral protruding boss 2| that is bored to slidably fit the bar I1 andform a sleeve of considerable length that is rotatably and slidablymovable along the bar for securely holding the guiding surface of theplate 14 parallel to the direction of movement of the plate 8.

The bar I! is provided with teeth 22. The bracket arm I5 is providedwith a pinion 24 that is disposed in a recess 25 formed in the boss 2|and in position to engage the teeth 22 of the bar II when themeat-slicing regulator plate is located in such a position that itoverhangs the bed of the machine, as shown in Figs. 1 and 2. The pinion24 is rotatably supported in the boss 2| by means of a shaft or pin 26,and a handle 21 is connected to the pin 26 for rotating the pinion 24 tomove the bracket and the plate along the bar H. The handle 21, is thus,conveniently located, with reference to the operator, when slicing themeat. Consequently, the plate may be adjusted, with reference to the saw5, to produce desired thickness of the slice as the meat is carried bythe plate 8 along the surface of the plate l4 and against the saw 5.

The bracket arm I5 is, also, provided with a locking screw which extendsinto one end of the bracket arm to engage the pin 26 and releasablysecure the pin 26 when the bracket has been shifted along the bar I!tothe desired position, with reference to the saw 5 by the operation ofthe handle. Thus,'when a number of slices, having substantially the samethickness, are to be cut, the locking screw may be turned to clamp thepin 26 and, thus, secure the plate l4 in a fixed position during thesawing operations of the machine.

The bar I! is provided with a plane surface 3| that is locatedcontiguous and substantially at right angles to the bottoms of thevalleys between the teeth 22 to enable rotation of the a bar secured tothe bed and having gear teeth;

bracket arm and the plate I 4 about the bar I I or, more particularly,to enable the teeth of the pinion 24 to slide from the teeth 22 of thebar I1 and move to a position to overhang the surface 3|, and in spacedrelation thereto. This occurs when the bracket arm I! is disposed in theposition shown in Fig. 4 and the plate I is disposed remote from the bed2 of the machine The bracket arm l5 and the plate ll may then bemanually slid along the bar i'l without rotation of the pinion 24.

In order'to support the plate It in the position where it overhangs thebed 2 and, also, to support the plate It in the position remote from thebed, the bracket arm is provided with a pair of stops 32 and 24, whichengage the ledge II. The stop I2,in the particular machine shown,engages the vertical side 35 01' the ledge when the plate It issupported above the bed 2, in the position shown in Fig. 2, and the stop34 engages the horizontal sidell oi the ledge when the plate I is swungaway from the bed 2 of the machine and is disposed in the position shownin Fig. 4. The stops I2 and 34 are readily slidable along the ledge whenin engagement therewith.

The construction, thus, aflords a means whereby the plate ll may bereadily manipulated with reference to the bed 2 of the machine to enableready manipulation of the machine to cut slices of meat or to outdifferent sizes of meat, or to cut from a carcass.

I claim: 1. In a meat-sawing machine, a machine bed;

a meat-guide plate a bracket member connected to the plate forsupporting the plate for pivotal and slidable movements on the bar andhaving a pinion rotatably supported in the bracket and adapted to engagethe teeth 01' the bar; ahandle connected to the pinion for rotating thepinion to adjustably move the plate relative to the machine bed; the barhaving a plane surface contiguous to the ends of th teeth of the bar toenable rotation of the pinion, the bracket and the plate. v

2. In a meat-sawing machine, a machine bed having a ledge; a bar securedto the bed and extending substantially parallel to and below the ledgeand having gear teeth; a meat-guide plate; a bracket member connected tothe plate for supporting the plate for pivotal and slidable movements onthe bar and having a pinion rotatably supported in the bracket andadapted to engage the teeth of the bar; a handle connected to, thepinion for rotating the pinion to adjustably move the plate relative tothe machine bed; the bar having a plane surface contiguous to the endsof the teeth to enable rotation of the pinion, the

bracket and the plate; a pair of stops located on the bracket forengaging the ledge when the bracket is rotated on the bar and coactingwith the bar for slidably supporting the plate in position overhangingthe bed and in position re- Q moved from the bed.
